Original application led August 22, 1914, Serial No. 858,009. Divided and this application ler January To all whom t may concern:

Be it known that I, AUGUST BOUOHERY, a citizen of the United Statesresiding in the borough of Brooklyn, in the county of Kings, city and State of New York, have invented new and useful Improvements in Portable Electric-Lamp Stands, of which the following is a speciiication.

This invention relates to portable electric lamp stands, and it is the primary object of the invention to provide a lamp stand of this character having means to clamp and support the Stand from a suitable support, such as a bedstead, dresser, chair, desk vor other obj ect, and to provide a stand with a suction supporting device to Sustain the stand from a non-porous Surface at an angle to the horizontal.

The present application is a division of my co-pending application filed August 22, 1914, Serial No. 858,009, Patent 1,132,532, March 16, 1915, covering a lamp of this character in which the parts may be readily and quickly disassembled and packed into a small, neat and compact structure to take up a minimum amount of space, the supporting base and a shade for the lamp being constituted to be releasably connected to form a receptacle in which to inclose a lamp Socket, a connecting plug and a length of electric current conductors to the ends of which the lamp socket and plug are connected, the lamp base and shade when connected to form a receptacle also inclosing and concealing the shade supporting means connected to the shade and the means to clamp the stand to a Support and to sustain it from a non-porous surface. Y

The principal object of the present invention is to provide novel means, in the form of a spring normally housed and concealed by the base to permit of setting the stand upon a iiat Surface and coperating with the base as a clamp, to support the Stand from a suitable object, and to the Slidably mounting of a lamp supporting stem in the base, the inner end of said' stem being connected to the clamping spring in the base and normally maintained in its upper position by said spring. A suction supporting device is connected to the lamp supporting stem within the base, the tension of the spring when the stand is supported by the Y suction device exerting an outward push on Serial No. 1,558.

vation, partly broken away, to illustrate the manner of Sustaining thestand vfrom a surface at 'an angle to the horizontal by means l' of the suction device. Fig. 4 is a bottom view of the shade. Fig. 5 is a side elevation Showing the manner of constructing the lamp supporting stand to permit of the tilting of the lamp to an angle relative to the axis of the lamp supporting stemg'and Fig. 6 is a sectional sideelevation showing the base and shade connected with the socket, plug, current conductor and the lamp stand and shade supporting means inclosed and concealed by the base and shade.

Similar characters of reference designate like parts throughout the different views of the drawings.

In the embodiment of my invention illustrated in the drawings I have shown the same as consisting of a. base B substantially of bell-shape with the bottom flaring out, and a shade S substantially of dome-shape having means, Suchras apair of resilient or yielding loops 7, to Support the shade from a globe or bulb at opposite sides to have adjustment about the longitudinal aXiS of the lamp and also to any angle on an axis transverse to the bulb. 'Ihe shade is constructed of a suitable resilient or yielding material andthe periphery of the bottom is of slightly greater diameter than the bottom of the base to permit it to engage over the bottom of the base, and the bottom voi' the shade is so constructed that portions thereof, as at s, in the form of inwardly extending projections will yieldingly engage with the base. As the shade and base are being connected the material of the shade will give or spring and when connected the projections will releasably hold the shade to the base. A stem 8 is slidably mounted in the top of the base, and a transverse member 11 in the form of a disk having an opening concentric with the opening in the top of the base is fastened in the base providing a long bearing for the stem and preventing canting thereof, and to which stem a lamp socket 9 is adapted to be removably connected.

To support the lamp stand from an 0bject, such as a bedstead, dresser, chair or the like, I provide a clamping member to cooperate with the base as a clamp. This member consists of a coiled spring 10 inclosed by and connected to the base and preferably wound to conform to the base. The inner coil or whirl of the spring is oonnected to the stem 8 within the base and the outer coil or whirl engages in a bead at the bottom of the base, as shown at 12, Figs. land 6. The spring at a point between the ends is fixed to the base as by soldering, as shown at 13, Figs. 1 and 6. By this construction a whirl or whirls of the spring adjacent the lower end may be pulled out from the base to engage an object o and cooperate with the base as a clamp to firmly secure the lamp to such support, as shown in Fig.V 2. The coils of the spring adjacent the upper end and secured to the stem 8 tend to maintain the stem in itsy uppermost position but permit said stem to be pushed into the base for a purpose to be hereinafter described.

The stem 8 at its end within the base and within the spring has a suction supporting device, such as a suction cup of rubber 14, to support the lamp from a surface which is at an angle to the horizontal, as shown in Fig. 3. To cause the suction cup to engage with the supporting surface the stem 8 is pushed inward against the tension of the upper coils of the spring forcibly pressing the suction cup against the surface. As the pressure is released on the stem the spring will exert an outward pressure on the stem and constantly exert a pull on the suction cup. This pull on the cup facilitates the holding` of the lamp by the cup as it constantly tends to create a vacuum in the cup. Furthermore, the tension of the spring presses the bottom of the base firmly against the supporting surface, whereby the base serves as a backing to prevent sagging and wabbling of the lamp.

As stated the lamp socket is removably connected to the stem 8 and is adapted to be connected thereto to extend co-axially with the stem or at an angle thereto. For this purpose the stem 8 is made of a pair of sections pivotally connected, as at 15, to swing on an axis transverse to the axis of the stem. The free end of the outer stem section is provided with screw threads 17. The socket has a tubular portion 19 internally screw threaded to engage over the end of the stem 8 and the screw threads on the stem and tubular socket portion are so constituted that by giving the socketla partial rotation it will be firmly connected to the stem.

The socket is connected to one end of current conductors 20, the other end of which are connected to a plug 21 to connect the lamp to the source of current at some distance away from the place where the lamp is to be used. The conductor, socket and. plug are adapted to be placed into the i shade and be inclosed thereby when it is connected to the base, the spring 10 lying contiguous to the inner surface of the base permitting the shade supporting loops 7 to engage within the coils of the spring, as shown in Fig. 6. Y

From the foregoing description it will be obvious that I have produced a portable electric lamp which can be disassembled and packed into a compact structure to take up a minimum amount of space, for instance as shown by the dotted lines 22 in Fig. 6, in a traveling bag or case.

Variations may be resorted to within the scope of my invention.
